Feasibility and implementation of a grocery shopping intervention for adults diagnosed with or at-risk for type 2 diabetes.

Objective: To examine the feasibility and implementation of an optimal defaults intervention designed to align grocery purchases with a diet recommended for people with or at-risk for type 2 diabetes.

Design: This was a 5-week pilot randomised trial with three groups: in-person grocery shopping, shopping online and shopping online with 'default' carts. Participants were asked to shop normally in Week One, according to group assignment in Weeks Two-Four (intervention period), and as preferred in Week Five.

Effects of a grocery shopping intervention designed to improve diet adherence in diabetes: a randomized trial.

Objective: The goal of this study was to examine the potential of an optimal-defaults intervention to promote grocery purchases corresponding to a diet for diabetes.

Methods: In total, 65 adults diagnosed with or at increased risk for type 2 diabetes who grocery shopped at one of two study stores were randomized to one of three groups: Defaults, Online, or Control. All groups received diabetes-friendly recipes.
